| Description
Quantum single-photon detectors (SPADs) are highly sensitive devices designed to detect and measure individual qubits/photons, playing a crucial role in quantum networks [1]. These detectors operate based on avalanche photodiodes (APDs). The ability to detect single photons with high temporal resolution is essential for quantum communications. Nevertheless, current SPADs are complex systems that need to be well assembled and characterized in order to have them operating in optimal conditions. To address these challenges, this project proposes to assemble a hardware transceiver to generate and detect single photons at optical frequencies, hereby utilizing measurement instruments to effectively model and evaluate its performance and scalability. In this direction, single-photon avalanche detectors will be employed due to their affordability, versatility, and flexibility, which serve as an ideal platform for implementing and modelling quantum transceivers. Methodology and Objectives to achieve The approach of the project follows the implementable methods for characterizing single photon avalanche diode detectors [2], [3]. Accordingly, the main objective of this research project is to model, assemble and characterize the emission and detection of attenuated laser pulses as single-photons. The specific objectives of this research project are: - Model attenuated laser pulses for Quantum communications. - Experimentally assemble and characterize the detector modules. - Characterize and discuss results, future work and limitations. Workplan First, at the modelling phase, the student will model single-photon detectors with the direction of the directors of the thesis. At the experimental stage the candidate will have access to hardware equipment to configure and evaluate the detector system. References [1] R. V. Meter, Quantum Networking, 1st edition.
